the last pair is statements are true.
Answer:
Area= 50√3 units^2
Step-by-step explanation:
Given:
In given triangle, there are two sides with length 10√3 and 20 along with angle of 30° between them.
As the given triangle is SAS triangle, we'll use the following formula to calculate its area:
A=1/2absinC
where a= 20
b= 10√3
and c=30°
Now putting values we get:
A=(1/2)(20)(10√3) sin(30)
=100√3(1/2)
=50√3
so the area is 50√3 units^2 !
The TV is 28% off. You can verify this by dividing 1022.4 by 1420 and getting 0.72. That's how much of the price you have to pay.
So you just subtract .72 from 1 to .28
